JBL Cinema 3635 LC-SUB 18" Pro System Subwoofer
The JBL 3635 LC-SUB is a cinema-grade subwoofer built for live venues, theater systems, and installations where controlled, articulate bass reinforcement is non-negotiable. Its shallow profile cabinet fits discreetly behind projection screens or into tight venue spaces while delivering the low-frequency performance required in high-end commercial and theatrical environments. This unit combines JBL's professional engineering with practical real-world installation constraints.
Design & Build Quality
Built with a compact footprint of 46 x 25.625 x 14.5 inches, the shallow cabinet design minimizes the space required behind-screen or in cramped venue setups while maintaining structural integrity at 113 lb. The barrier strip screw terminals provide secure, professional-grade connections suitable for permanent installations and quick integration into existing sound systems.
Audio Performance
The 460 mm (18-inch) low frequency driver delivers a frequency range of 38–100 Hz (±3 dB) with extended response down to 28 Hz at -10 dB, ensuring tight, articulate bass without muddiness in live and installed applications. Maximum SPL of 125 dB at 1 meter and 300W AES power handling enable this subwoofer to integrate seamlessly into theater systems and large-venue setups requiring controlled low-end reinforcement that holds up night after night.
